One thing that worries about Pogba's position going forward is Jose's ego. He's already argued back with the media about Pogba being able to play in a two man midfield. If he relents and starts Pogba in a 3 man midfield and it works, then it shows that he was wrong and everyone else was right all along.
Maybe I'm reading into it too much, but I'm wondering if Jose's stubbornness or wanting to come out on top of this debate might lead to him cutting off his nose to spite his face so to speak.
To be a great manager, you must not doubt yourself. On the other, Pogba can decide to zip up and do his job, will the media and everyone accept they were wrong?
